Acontainer holding 2.3 moles of br2 gas is st a pressure of 6.7 atm and has a volume of 14.2 l what is the temperature in k?

The  temperature  in K    is  503.84 K

  calculation

The temperature  in K is calculated using the ideal gas equation.

That is Pv = nRT

where

p(pressure)= 6.7 atm

V( volume) = 14.2 l

n( number of moles)= 2.3  moles

R( gas constant) = 0.0821 atm.L/K.mol

T( temperature)= ? K

make T the subject  of the formula  by  diving both side of equation by nR

T =PV/nR

T =[(6.7 atm x 14.2 l) /  (2.3 moles x0.0821 atm.l/k.mol)]  = 503.84 K

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.

it would only be the stuff in module eight so you need to study all the lessons in that you also could check the flvs

hope this : )
